Packaging is a necessary condition for products to enter the circulation field, and the main means of achieving packaging is the use of packaging machinery. With the development of the times and the advancement of technology, packaging equipment is playing an increasingly important role in the packaging field. Its main functions are as follows:
        (1) can greatly improve labor productivity
        Mechanical packaging is much faster than manual packaging. For example, candy packaging can only pack more than a dozen pieces in 1 minute, while candy packaging can reach hundreds or even thousands of pieces per minute, increasing efficiency by dozens of times.
        (2) can effectively guarantee the quality of packaging
        According to the requirements of the packaging, the mechanical packaging can obtain the packaging with the same specifications according to the required shape and size, and the manual packaging cannot be guaranteed. This is especially important for export goods. Only mechanical packaging can achieve standardization and standardization of packaging, and meet the requirements of collective packaging.
        (3) can achieve the operation that manual packaging can not achieve
        Some packaging operations, such as vacuum packaging, inflatable packaging, body packaging, etc., are all impossible to achieve by hand packaging, and can only be achieved.
        (4) can reduce labor intensity and improve working conditions
        Manual packaging is labor intensive. For example, it is labor-intensive and unsafe to manually package large and heavy products. For light and small products, due to the high frequency and monotonous movement, workers are prone to occupational diseases.
        (5) Labor protection for workers
        For some products that seriously affect your health, such as dusty and toxic products, irritating and radioactive products, it is inevitable to avoid health hazard by hand packaging, while mechanical packaging can avoid it and effectively protect the environment from pollution.
        (6) can reduce packaging costs and save storage costs
        For loose products, such as cotton, tobacco, silk, hemp, etc., compression packaging with a compression packaging machine can greatly reduce the volume, thereby reducing packaging costs. At the same time, due to the large size reduction, saving storage capacity, reducing storage costs, and facilitating transportation.
        (7) Reliable product hygiene
        Some products, such as food and medicine packaging, are not allowed to be packaged by hand according to the hygiene law, because they will contaminate the product, and the mechanical packaging avoids direct contact with food and medicine, ensuring the quality of hygiene.
        (8) can promote the development of related industries

        Packaging machinery is a comprehensive science, which involves materials, processes, equipment, electronics, electrical appliances, automatic control and other disciplines, requiring all relevant disciplines to develop synchronously and harmoniously. How the problems of disciplines will affect the whole machine of packaging machinery performance.
